昨天学了一天的Python（我的生产语言是java，也可以写一些shell脚本，算有一点点基础），今天有一个应用场景，就正好练手了。
这个功能之前再java里写过，比较粗糙，原来是在我本机跑的，今天老大要求要随时保持请求，就用Python改写了下，省的又把一个有跟多杂项的jar包传到服务器，省空间又不乱，而且好读。
先附上java代码：
package xxxxxx.base;
import java.util.Random;
import org.apache.commons.lang3.StringUtils;
import haojianxiang.util.HttpRequest;
public class CreateFeedbackData {
public static void main(String[] args) {
while (true) {
try {
Random r = new Random();
int sleep = r.nextInt(1200000) + 600000;
Thread.sleep(sleep);
post();
}
catch (Exception e) {
e.printStackTrace();
}
}
}
public static void post(){
String url = "http://111.111.111.111:8080/xxxx/post";
int[] types = {
1, 2, 3, 4}
;
int index = (int) (Math.random() * types.length);
int type = types[index];
// String[] contents = {
"-中文测试-，","-English Test-,","~!@#$%^&*()_;
:'-"<>?/|\-,"," "}
;
String[] contents = {
"-中文测试-，","-English Test-,","~!@#$%,"," "}
;
StringBuffer content = new StringBuffer();
content.append("haojianxiang test:");
for (int i = 0;
i < 10;
i++) {
int idx = (int) (Math.random() * contents.length);
content.append(contents[idx]);
}
String[] imgs = {
"/Upload/appUpload/58c7b315cb39f.jpg", "/Upload/appUploa/58cb467a69873.jpg", "/Upload/appUpload/58afff0e99432.png", "/Upload/appUpload/58b545539eb80.jpg", "/Upload/appUpload/58b55d7c9e281.JPG", }
;
StringBuffer img = new StringBuffer();
for (int i = 0;
i < (int) (Math.random() * 4);
i++) {
int lucky = (int) (Math.random() * 2);
if (lucky == 1) {
int idx = (int) (Math.random() * imgs.length);
img.append(imgs[idx]);
img.append(",");
}
}
String imgStr = "";
if (StringUtils.isNotBlank(img)) {
imgStr = img.substring(0, img.length()-1);
}
String param = "{
"req":{
"userId":xxxxxx}
," + ""data":{
""fbType":" + type + ","fbContent":""+content.toString()+ "","fbPic":""+imgStr+""}
}
";
String rst = HttpRequest.sendPost(url, param);
System.out.println("TIME--"+ System.currentTimeMillis() + " result:" + rst);
}
}
(代码里的参数地址等我已做了隐藏，json格式可能不准确了，无所谓)
接下来上Python代码：
#!/usr/bin/env python # -*- coding: utf-8 -*- import random import urllib import urllib.request import time def postFeedBack(): url = "http://111.111.111.111:8080/xxxx/post" type = int(random.uniform(1,5)) contents = ["-中文测试-，","-English Test-,","~!@#$%,"," "] content = "haojianxiang test:" for i in range(0,10): content += random.choice(contents) img = "" imgs = ["/Upload/58c7b315cb39f.jpg", "/Upload/58cb467a69873.jpg", "/Upload/58afff0e99432.png", "/Upload/58b545539eb80.jpg", "/Upload/58b55d7c9e281.JPG"] for i in range(0,3): lucky = int(random.uniform(0,2)) if lucky == 1: img += random.choice(imgs) img += "," img = img[:-1] data = "{
"req":{
"userId": xxx}
," data += ""data":{
data += ""fbType":" data += str(type) data += ","fbContent":"" data += content data += "","fbPic":"" data += img data += ""}
}
" pdata = bytes(data,encoding="utf-8") f = urllib.request.urlopen(url,pdata) result = f.read() result = result.decode('UTF-8') print(result) if __name__ == "__main__": while True: st = int(random.uniform(600,1800)) print("sleep:",st) time.sleep(st) postFeedBack()
Python的写法确实很简洁高效（java代码里post的逻辑，我还是调用了自己的一个工具类，实际代码要更多），今后打算把Python作为优先脚本语言，处理简单问题很快。
